Description
L4~3~
The invention rela-tes to a remote control starter assembly for remotely starting an engine of a vehicle~ More specifically, the invention relates to such an assembly which does not require installation, and which may include an alarm system.
Presently available remote control starter systems are -typically permanently installed in the cars. These systems are complex, and as they must include sensors for sensing different conditions in the car, they can be installed only by trained mechanics. As a result, these systems are expensive to purchase and expensive to install.
In addition, as -these systems are permanently installed, the car, would, at all times, be driven with the system installed. Under such conditions, car manufacturers will not accept liability for failure of, for example, the starter motor even during the guarantee period as such failure could result from failure of the remote control starter system. Thus, the remote control starter system could start spontaneously and burn out the starter motor.
; 20 It is therefore an object of the invention to provide a remote control starter assembly for remotely start-ing an engine of a vehicle which does not require installation.
It is a more specific object of the invention to provide such an assembly which may include an alarm system.
It is a still further object of the invention to provide such an assembly which can be used in automobiles, trucks, buses, and the like.
In accordance with the invention there is provided a remote control starter assembly for remotely starting an engine of a vehicle, said vehicle including an ignition 2~29L~
switch having a key hole and having OFF, IGNITION and E~GINE
RUN positions, an ignition key insertable into said key hole in said ignition switch and adaptable to change the positions of said ignition switch by rotation thereof;
said remote control starter assembly comprising:
means for releasably grasping said key when said key is inserted in said key hole;
means for receiving a coded signal; and means for rotating said means for grasping said key, said means for rotating being activated by said means for receiving a coded signal upon receipt of an appropriately coded signal.
The invention wil-l be better understood by an examination of the following description, together with the accompanying drawings, in which:
FIGURE 1 is a top view of the inventive system mounted around the steering column of an automobile;
FIGURE 2 is a section through II-II of Figure l;
.
FIGURE 3 is a bloc~ diagram of the electronic control unit of Figure 1; and FIGURES 4A and 4B illustrate a flow chart of the program driving the electronic processor of the electronic control unit.
Referring to Figure 1, the assembly, illustrated generally at 1, comprises a housing 3 for housing the . assembly. In the Figure 1 embodiment, the assembly is mounted around a s-teerlng column 5 of the vehicle, and the assembly includes a means for releasably grasping key 7 when the key 7 has been inserted in-to key hole 9 of the ignition switch of the vehicle.
4~
As seen in Figures 1 and 2, the means Eor releas-ably grasping in the illustrated embodiment comprises a gear 11 which meshes with a gear 13 which is driven by shaft 15 of motor 17. As seen in Figure 2, the gear 11 includes a central opening 19 into which the head of key 7 is insertable.
Accordingly, it can be seen that the key 7 will rota-te with the rotation of the motor 17. The motor 17 is preferably a DC motor which will be driven in one direction when power of one polarity is applied thereto, and which will be driven in the opposite direction when power o~ the opposite polarity is applied-thereto. Thus, key 7 can be rotat:ed both clockwise and counter-clockwise.
The assembly also includes an electronic control system 21. As seen in Figure 3, the electronic control system 21 includes a radio receiver/transmitter 23, an electronic processor 25, a rechargeable battery 27, an alarm means 28 and a cigarette lighter plug-in unit 29. The cigaret~e lighter plug-in unit is plugged into the cigarette 2~ lighter plug whereby the car battery will provide driving power for driving the various elements of the assembly. The alarm means 28 is driven by the rechargeable battery 27 through the electronic processor 25 for reasons to be discussed below.
In the illustrated embodiment, where the ignition switch is in the steering column, the assembly housing 3 preferably is in the shape of a yoke having a ~irst arm 31 and a second arm 33 and a hinge 35. The yoke is openable about the hinge 35 to be placed around the steering column in such a position that the head of the key 7, when it is inserted into the ignition switch key hole 9, will be ;~2~ ".
inserted into the opening 19 of gear 11. Arms 31 and 33 are then brought -together, and one arm of a hasp 41 of a lock 43 is inserted through aligned openings 37 and 39 whereby the yoke is locked to the steering column. Obviously, if the ignition switch is on the dashboard instead of on the steer-ing column, then a different type of housing will be needed for removably fixing the assembly adjacent the ignition switch key hole.
In considering the operation of the assembly, it is ~o noted that, when the ignition switch is not turned on, then the battery voltage which is sensed by the cigarette lighter plug-in uni-t will be high, and the ripple frequency on the battery will be low or non-existent. At this time, the key is in the OFF position of the ignition swi-tch.
When the key is rotated to the IGNITION position of the ignition switch, to start the starter motor, the voltage sensed by the cigarette lighter plug-in unit will drop, and the ripple frequency on the battery will be of an inter-mediate value corresponding to the speed of the star-ter motor.
When the engine of the vehicle begins to rotate, then the voltage rises again and the ripple frequency on the battery is very high corresponding to the rotational speed of the vehicle engine. Accordingly, it is possible to monitor the condition of the engine by monitoring the voltage and ripple frequency of the battery through the cigarette lighter plug-in unit 29.
Power from the vehicle battery is provided to the rechargeable battery 27 through the processor 25 to keep the battery recharged.
:
As is also well known, when -the vehicle engine has turned over and begins to rotate, then the starter rno-tor rnust be turned off or the starter motor will be damaged. For this to occur, -the key in the ignition switch must be rotated to the ENGINE RUN position of the ignition switch.
The assembly is controlled by a remote control unit which transmits coded signals as is well known in the art.
One of the coded signals comprises the START signal, the other one comprises the STOP signal and a third code comprises an ALARM DISENGAGE signal~
The electronic processor 25 will run through programmed cycles as per the flow chart in Figures 4A and 4B.
Concerning these flow charts, -the first condition which is monitored is the alarm condition. One of the alarm condi-tions is activated when the cigarette lighter plug-in unit is removed from the cigarette lighter plug before the alarm has been disengaged. The removal will be sensed by the electronic processor 25 which will connect the rechargeable battery 27 to the alarm means 28 to thereby sound the alarm.
As will be seen below, other alarm conditions may also be detected in different ways. However, when this alarm condi-tlon is detected, obviously, an auxiliary source of power needs to be provided to power the alarm means as the assembly is no longer connected to the vehicle battery.
Returning now to the flow chart, if an alarm condi-tion has not been detected, then the alarm disengage signal is monitored. If the alarm disengage signal is detected, then the processor will disengage the alarm means 28.
If neither the alarm condition nor alarm disengage condition have been detected, the processor monitors the STA~T signal. If the START signal has not been received, ~'. ' , ' :; ' .'~ ~ ,:
then the STOP signal is monitored. If this signal also has not been received, then the processor returns to the beginning of the cycle.
If the STOP signal has been received, then the DC
motor is turned on in such a direction, and for such a period of time, as to turn the ignition key 7 to the OFF position of the ignition switch.
If the START signal is received, then the battery voltage and the battery ripple frequency is checked through the cigarette lighter plug-in unit 29. If the battery voltage is not high, then there is a faulty condition, either of the battery or the starter motor, so that the transmitter of the receiver transmitter 23 is turned on to transmit a fault alert to the remote control unit. If the battery voltage is high and the ripple frequency is also high, then the engine is rotating so that no further action is required and the cycle can end. If the ripple frequency is low, then the electronic processor will provide power of such a polarity and such a duration to the motor 17 so that the ignition ~ey 7 will be rotated to the IGNITION position of the ignition switch.
The battery voltage and ripple frequency is once again monltored after the key has been rotated. If the battery voItage does not fall, then there is a fault some-where in the system and the key is rotated to the OFF posi-tion and a signal is transmitted on the receiver transmitter 23 to the remote control unit -to provide a fault alert.
If the battery voltage is low and the ripple frequency is low, this means that the star-ter motor is still rotating. The starter motor can be permitted to rotate for a period of only 5 seconds in order to avoid burn out.
Accordingly, under the latter conditions of low voltage and low ripple frequency, the elapsed time is moni-tored. If the elapsed time has not been exceeded, then the battery voltage and ripple frequency are once again monitored. If the period has elapsed or been exceeded, then, once again, the key is rotated to the OFF position and a fault alert is transmitted to the remote control unit.
If the battery voltage is low and the ripple frequency is high, this means that the vehicle engine has started to rotate so that the starter motor should be turned off. For this purpose, the key is rotated to the ENGINE RUN
position.
As a final check, -the battery voltage and ripple frequencies are once again tested. If either the voltage or the ripple frequency is not high, then a fault is indicated and the ignition key is turned -to the STOP position and a fault alert is transmitted to the remote control unit. If both are high, then the vehicle engine is running properly.
As an added security feature, the engine ~ill be shut-off after a predetermined period of time, for example, 5 minutes, has elapsed. For this purpose, the elapsed time keeps being monitored and as long as the predetermined period has not elapsed, the cycle simply ends. If the predetermined period has elapsed, then the key is returned to the STOP position so that the vehicle engine is turned off.
.
The assembly can be made small enough to be stow-able, when not in use, in, for example, the glove compartment of the vehicle. When the car is parked, the assembly would be mounted on the steering wheel with the ignition key in the ignition switch and the ignition key head in the assembly.
The assemb~y is locked into place so that it cannot be .
, . ~
~)2~
removed without physical violence. Wi-th the assembly mounted on the steering column as illustrated in Figure 1, the vehicle cannot be started using the igni-tion switch as the ignition key is locked to the STOP position of the ignition switch. In addition, it would be very inconvenient to drive the vehicle with the assembly mounted on the steering column.
Further, if the assembly is to be removed, then it will also be necessary to either remove the cigarette lighter plug-in unit from the cigarette lighter plug or to detach the cigarette lighter plug-in unit from the remainder of the assembly. Either of these conditions would be detected and an alarm would be sounded. Accordingly, there is provided security for the vehicle when it is parked and when the assembly is mounted on the steering column.
When the vehicle is again to be used, the remote control unit is activated to transmit a START coded signal.
this will start the car. Before entering the car, the user ~; ~ will then activate the remote control unit to transmit an alarm dlsengage signal. Accordingly, it will be possible to remove the cigarette lighter plug-in unit without sounding an alarm. The vehicle owner can then remove the assembly from the steering column and stow it in, for example, the glove compartment while the vehicle is being driven. Accordingly, contrary to presently available remote control start systems, the assembly of the present invention is not connected when the ve~hicle is operational.
The assembly can also include a car brea~-in delector. For this purpose, if any of the car doors are opened when the car is parked, then an alarm signal would be emitted by means well known in the art, and the emitted : : ~
~ .
signal would be received by the receiver/transmitter 29 of the assembly. Accordingly, an alarm condition would be detected and the alarm would be sounded.
Although particular embodiments have been des-cribed, this was for purpose of illustrating, but not limit-ing, the invention. Various modifications, which will come readily to the mind of skilled in the art, are within the scope of the invention as defined in the appended claims.
